- 1. A process for producing a flowable form of the dipeptide sweetener L-aspartyl-L-phenylalanine methyl ester, which form has a high rate of solubility and dispersibility, comprising the steps of:
- (a) forming an aqueous slurry, the ingredients consisting of water and a minor weight percent of crystalline particles of L-aspartyl-L-phenylalanine methyl ester;
- (b) maintaining said slurry at a temperature below 150.degree. F. such that the vast majority of the crystalline material remains as undissolved particles and a minor amount of this material dissolves in the water with the resulting solution being distributed throughout the undissolved particles;
- (c) hydro-milling the slurry to a particle size of less than 125 microns; and
- (d) spray drying the milled slurry to produce a dry powder wherein subdivided discrete crystals of the dipeptide sweetener nest with one another and are permanently bound to one another at spaced points of contact by the dried solution.
